In brief – super violent, misogynistic, homophobic, white guy hip-hop act just announced they were Christian evangelicals and this was all part of their plan.

Violent J explained himself unapologetically to a New Jersey newspaper: “You have to speak their language. You have to interest them, gain their trust, talk to them and show you’re one of them. You’re a person from the street and you speak of your experiences. Then at the end you can tell them: God has helped me.”
Of course, one might argue that 20 years was, under the circumstances, an incredibly long time for them to have pretended to be unholy, and that, from a Christian perspective, the harm they did while feigning unholiness may even have outweighed the greater good.
